The invention relates to a motor, and particularly relates to an automobile radiator fan motor assembly. According to the technical scheme, the automobile radiator fan motor assembly comprises a shell, a rotor arranged in the shell, a stator and an end cover; the rotor comprises a rotary shaft arranged in the shell in an erection manner, and a magnetic shoe arranged on the rotary shaft in a sleeving manner; an output hole for allowing the rotary shaft to extend to the outside of the shell is formed in the other end, relative to one end connected with the end cover, of the shell; a mounting base integrally formed with the end cover is arranged in a position, corresponding to the output hole of the shell, of the end cover; a mounting hole which is concentric with the output hole and used forallowing the rotary shaft to be inserted is formed in the mounting base; a bearing is arranged between the mounting hole and the rotary shaft; a ball bearing is arranged between the output hole and the rotary shaft; a supporting base fixed with the end cover is arranged between the mounting position in the magnetic shoe of the rotary shaft, and the mounting base; and a ball positioning bearing isarranged between the supporting base and the rotary shaft. By adoption of the technical scheme, the automobile radiator fan motor assembly which is capable of lowering noise, simple in structure andconvenient to assemble is provided.
Description
technical field [0001] The invention relates to a motor, in particular to an automobile radiator fan motor assembly. Background technique [0002] The car radiator fan motor is the driving source for driving the radiator fan. A traditional fan motor is mainly composed of a casing, a rotor disposed in the casing, a stator fixed on the inner wall of the casing and arranged around the rotor, and an end cover. [0003] However, noise, vibration and harshness are a comprehensive issue to measure the quality of automobile manufacturing. The traditional fan motor assembly cannot effectively reduce the resonance between the fan and the fan casing when the fan rotates, thereby increasing the generation of noise. [0004] Therefore, how to reduce the noise of the fan motor assembly during use has always been a direction and a difficult problem for technicians in this field to continuously research and develop. Contents of the invention [0005] Aiming at the deficiencies in the p...
